Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of optical film processing equipment, specifically a winding structure for an optical film coating machine. Background Technology
[0002] The characteristics of optical thin films are: smooth surface, geometrically segmented interfaces between film layers, anisotropy of thin films due to film growth, structure, stress and other factors, and complex time effects.
[0003] Currently, when operators process optical films using coating machines, they often need to use a winding structure. However, while the existing winding structure has basic winding functions, operators need to clean the outer surface of the optical film during the winding process. Since the cleaning rollers on the winding structure are fixed, they cannot meet the operator's needs when cleaning the outer surface of optical films of different thicknesses, thus reducing the scope of application. Therefore, improvements are needed. Utility Model Content

This utility model, by setting a second motor, a bidirectional threaded screw, a slider, and a long rod, allows the operator to start the second motor, which will cause the bidirectional threaded screw to rotate, thereby causing the two sliders to move towards each other. This, in turn, causes the two long rods to rotate and push the long plate upward as a whole, thereby increasing the tension of the optical film located at the top of the outer surface of the motion roller. This keeps the optical film in a taut state during the winding process, thus avoiding wrinkles caused by surface looseness during winding. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a winding structure for an optical film coating machine, including a worktable 1. A first connecting plate 2 and a second connecting plate 31 are fixedly connected to the left side of the top of the worktable 1 in the front-rear direction, respectively. A first circular shaft 3 and a movable shaft 4 are movably installed inside the first connecting plate 2 and the second connecting plate 31, respectively. The back of the movable shaft 4 passes through the second connecting plate 31 and extends to the outside of the back of the second connecting plate 31, and a movable block 8 is movably sleeved on its outer surface. A first cleaning roller 6 is fixedly connected between the opposite faces of the first circular shaft 3 and the movable shaft 4. Inside plate 31, a second round shaft 5 is movably installed directly above the first round shaft 3 and the movable shaft 4. A second cleaning roller 30 is fixedly connected between the second round shaft 5. A dust-collecting cloth 7 is fixedly sleeved on the outer surface of the first cleaning roller 6 and the second cleaning roller 30. A first motor 9 is fixedly installed on the left side of the back of the workbench 1. A rotating shaft 10 is fixedly sleeved on the other end of the output shaft of the first motor 9. A hollow block 11 is fixedly sleeved on the outer surface of the rotating shaft 10. A moving shaft 12 is movably connected inside the hollow block 11. The front of the moving shaft 12 is fixedly connected to the back of the moving block 8.
[0023] When the operator starts the first motor 9, the rotating shaft 10 and the hollow block 11 will rotate, causing the inner surface of the hollow block 11 to press and push the outer surface of the motion shaft 12. This causes the motion shaft 12 to drive the moving block 8, the movable shaft 4, the first cleaning roller 6 and the first circular shaft 3 to move downwards. This increases the distance between the first cleaning roller 6 and the second cleaning roller 30, allowing the two vacuum cloths 7 to clean the surfaces of optical films of different thicknesses.
[0024] Among them, a rectangular block 13 is fixedly connected to the front and back of the top of the workbench 1, located to the right of the first connecting plate 2 and the second connecting plate 31. A moving block 14 is movably connected inside the rectangular block 13. A long plate 15 is fixedly connected to the top of the moving block 14. A mounting bracket 16 is fixedly connected to the front and back of the top of the long plate 15. There are two mounting brackets 16, and a connecting shaft 17 is movably installed inside the two mounting brackets 16.
[0025] When the long plate 15 moves upward, it will cause the two moving blocks 14 to move upward together.
[0026] There are two connecting shafts 17, and the opposite faces of the two connecting shafts 17 are fixedly connected to the moving rollers 18. The front and rear ends of the moving rollers 18 are movably connected to the opposite faces of the two mounting brackets 16.
[0027] When the motion roller 18 rotates, it will drive the two connecting shafts 17 to rotate together.
[0028] The second motor 19 is fixedly installed in the middle of the back of the workbench 1. The other end of the output shaft of the second motor 19 is fixedly sleeved with a bidirectional threaded screw 20. The other end of the bidirectional threaded screw 20 passes through the workbench 1 and extends into the interior of the front of the workbench 1. The front and rear sides of the outer surface of the bidirectional threaded screw 20 are threaded with sliders 21. The outer surface of the sliders 21 is movably connected to the interior of the workbench 1. The top of the sliders 21 is hinged with a long rod 22. The top of the long rod 22 is hinged to the bottom of the long plate 15.
[0029] When the operator starts the second motor 19, the bidirectional threaded screw 20 will rotate, causing the two sliders 21 to move towards each other, which in turn causes the two long rods 22 to rotate and push the long plate 15 upward.
[0030] Among them, the second mounting plate 24 and the first mounting plate 23 are fixedly connected to the front and back directions of the top right side of the workbench 1, respectively. The third motor 25 is fixedly installed on the front of the second mounting plate 24. The other end of the output shaft of the third motor 25 is fixedly sleeved with a rotating shaft 26 located inside the second mounting plate 24. The outer surface of the rotating shaft 26 is movably connected to the inside of the second mounting plate 24.
[0031] When the operator starts the third motor 25, the rotating shaft 26 will rotate.
[0032] The other end of the rotating shaft 26 is fixedly connected to a take-up roller 27. Both the front and rear ends of the take-up roller 27 are movably connected to the opposite surfaces of the second mounting plate 24 and the first mounting plate 23. The back of the take-up roller 27 is fixedly connected to a circular block 28 located inside the first mounting plate 23. The outer surface of the circular block 28 is movably connected to the interior of the first mounting plate 23.
[0033] When the rotating shaft 26 rotates, it will drive the take-up roller 27 and the circular block 28 to rotate together.
[0034] The workbench 1 has four legs 29 fixedly connected to the four corners at the bottom. The four legs 29 are the same size.
[0035] The design of the four table legs 29 provides excellent support for the entire workbench 1.
[0036] Working principle and usage process of this utility model:
[0037] First, the operator passes the optical film between the two dust-collecting cloths 7, places it on the top of the outer surface of the motion roller 18, and finally wraps it around the outer surface of the take-up roller 27. Then, the operator starts the second motor 19 and the third motor 25. The operation of the second motor 19 causes the bidirectional threaded screw 20 to rotate, which causes the two sliders 21 to move towards each other inside the worktable 1. This causes the two long rods 22 to rotate and push the long plate 15 upward as a whole, thereby increasing the tension of the optical film at the top of the outer surface of the motion roller 18. This keeps the optical film in a taut state during the subsequent winding process, thus avoiding wrinkles caused by the looseness of the optical film surface during the subsequent winding operation. The operation of the third motor 25 causes the rotating shaft 26, the take-up roller 27, and the circular block 28 to rotate, so that the take-up roller 27 can perform the winding operation on the optical film.
[0038] Finally, when the operator needs to rewind and clean optical films of different thicknesses, the operator starts the first motor 9, which will cause the rotating shaft 10 and the hollow block 11 to rotate. This causes the inner surface of the hollow block 11 to press and push the outer surface of the motion shaft 12, which in turn causes the motion shaft 12 to drive the moving block 8, the movable shaft 4, the first cleaning roller 6 and the first circular shaft 3 to move downwards. This increases the distance between the two first cleaning rollers 6, allowing the two dust-collecting cloths 7 to clean the outer surface of optical films of different thicknesses, thus bringing convenience to the operator.
